On the next slide is four reactions ( you will need to answer one question) Classify them as synthesis, decomposition, single replacement, double replacement, or combustion. Call me in when you are done
Pb(NO 3 ) 2 + 2HCl PbCl 2 + 2HNO 3 Type: Double Replacement 2C 2 H 6 + 7O 2 4CO 2 + 6H 2 O Type: Combustion Ca + 2HCl CaCl 2 + H 2 Type: Single Replacement 2SO 2 + O 2 2SO 3 Type: Synthesis Pb(NO 3 ) 2 + 2HCl PbCl 2 + 2HNO 3 Type: Double Replacement 2C 2 H 6 + 7O 2 4CO 2 + 6H 2 O Type: Combustion Ca + 2HCl CaCl 2 + H 2 Type: Single Replacement 2SO 2 + O 2 2SO 3 Type: Synthesis
